7 Claims.

My invention relates to an arrangement of rigging and a rigging connector element adapted pendently to support a high lead block by a length of cable upon a spar tree or similar support in logging. The principal object of myl invention is to provide a rigging connector element designed to accomodate a length of cable having enlarged ferrules secured to the ends thereof. Said rigging connector element is adapted to receive said ferruled ends of the cable expeditiously and to hold them securely. The rigging connections are arranged so that after said ferruled ends of the cable are seated in appropriate recesses therefor, and a high lead block is secured in place by a bolt connected to the shackle thereof, said ferruled ends are prevented from being removed until after said high lead block is rst detached.

A further and more specific object of my invention is to provide a rigging connector element of this character which is adapted to accommodate some angular movement of the ferruled ends, not only to provide articulation; but also to be tted to spar trees of different diameters. To this end I provide recesses adapted to receive the ferruled end of the cable through an open mouth thereof and a' slot formed at one side cable laterally, but to prevent a ferruled end passing therethrough. The walls of said recess converge from the open mouth thereof towards the socket end for engaging one end of the ferrule seated therein and said latter end is rounded to provide an action more or less similar to av balland-socket joint.

Other and further details of my invention are hereinafter described with reference to the ac companying drawing in which: v

Fig. 1 is a view showing the Amanner in which a high lead block may be secured to a spar tree by means of a length of cable, a rigging connector element, and a shackle providing articulated connection between rigging connector element and said high lead block;

Fig. 2 is an elevation of said rigging connector element with one portion shown broken away and illustrating the manner in which the two ends of a ferruled length of cable lmay be` received and held by said rigging connector element; and

Fig. 3 is a longitudinal section view taken on a line 3-3 of Fig. 2, illustrating the manner in which one ferruled end of a length of cable may be seated vin a receiving socket.

My invention is adapted for use with a sec- 2 v tion of cable I or so-called wire rope, having ferrules 2 and 2 fixed to the ends thereof. Said actual'length of cable is selected such as to encircle a-spar tree 3. Said length of cable droops somewhat in looping about said spar tree and thus is adapted to be fixed about various diamf f etered trees. The rigging connection 4 with which my invention Yis specifically concerned, comprises an integral body 5, is more or less hollow. It has two obliquely disposed elongated recesses 6 and 6' formed therein. The angular disposition of said recesses is shown best in Fig. 2. The angular alinement of said rigging connection and the disposition of the recesses is arranged for a spar tree of a diameter, say thirty inches and the recesses are disposed with the ends of the cable and extending outwardly thereof. Said slot is adapted to pass a length of therefrom as is illustrated in Fig. 2. That portion of the exterior of the body lying between said recesses is indicated as 1. Said portion 'l is rounded, as is shown in gure, so as not .to dig into and scar the barked surface of a spar tree.

Extending substantially in alinement transversely of the open mouths Ea and 6a of recesses 6 and 6', respectively is a pair of alined fasten ing holes 8 and 8' adapted to receive va bolt .9 for passing through and securing shackle l0 for high lead block Il to the rigging connector element. When said bolt is fastened thru said fastening holes and is secured by nut 9a, neither of the ferrules may be forced out of their recesses. In other words, said bolt keys said ferrules in their recesses to prevent their retraction.

The sidewalls of recesses 6 and 6 converge from their open ends 6a and Ea', respectively thereof toward the rounded seats 6b and 6b' therein. That is, said recesses are yelongated and are of such length as to accommodate the length of the ferrules. The diameter of the said mouths is slightly greater than the diameterof the ferrules, while the diameter of the recess adjacent seats v6a and 6a corresponds substantially to the diameter of said ferrules. The inner ends 2a and 2a of each of said ferrules, respectively, are Y rounded, as are seats 5b and 6b', and thus some slight articulation is permitted for a ferrule in its recess. The degree of angular movement is limited by the outward nare of the walls of the recess.V This is provided yto accommodate strain imposed upon the rigging and also to cause the section of cable and the associated parts to fit spar trees varying substantially in diameter.

Formed upon one side of each of said recesses 5 and 6 is an elongated slot I2 of such width as to pass the section of cable, but to retain the ferrule. Thus when the bolt B is removed, as is shown in Fig. 2, the ferruled end of a cable may be arranged as is shown in Fig. 2 and pulled up so that the rounded end 2a of the ferrule may seat upon the seat 6b of the recess. When both ferrules are in place, the bolt 9 may be secured through holes 8 and 8' to prevent said ferrules from being withdrawn.

In practice, a rigging man or so-called highclimber causes the section of cable to be passed about the spar tree a substantial distance above enlarged ferrules secured to the ends thereof, said connector element comprising an integral, relatively at, hollow body of triangular contour, having two obliquely disposed elongated recesses formed therein extending diagonally toward two adjacent corners, respectively, each recess provided with a mouth at one end and a socket at the other, the mouths of each of said recesses being open and disposed adjacent each other and the third corner, each of said recesses having a slot formed at one side thereof adapted to pass said length of cable, but to retain a ferthe ground. The ends of said cable are secured l together in said rigging connector element, as has heretofore been described, and `then the high lead block with its shackle may be lifted into' place and secured by passing the bolt r9 through holes 8 and 8 and within the bight of said.

shackle, so that all of said parts are firmly and securely held.
